| Abstract: | Fixture planning is a crucial problem in the field of fixture
design. In this paper, the research scope and research methods of the computer aided fixture
planning are presented. Based on positioning principles of typical workparts, an ANN algorithm,
namely Hopfield algorithm, is adopted for the automatic fixture planning. Also, this paper leads
a deep research into the selection of positioning and clamping surfaces (or points) on workparts
using positioning clamping surface selecting rules and matrix evaluation of deterministic
workpart positioning. In the end of this paper, the methods to select positioning and clamping
elements from database and the layout algorithm to assemble the selected fixture elements
into a tangible fixture are developed. |
